from the description and figure of pilosus in having the 

 apparent second joint of antennae distinctly shorter than the 

 third, the elytra do not have "four deep impressions" on 

 each side of the base, the impressions there being minute 

 punctures only, and they are entirely glabrous except for 

 some sparse pubescence on the margins and tips. From the 

 description of castaneus it differs in being considerably larger, 

 and with very different antennae. 



Paussoceros cremastogastri, n. sp. 



Castaneous; parts of appendages lightly infuscated. Parts 

 of sterna and base of abdomen with dense pubescence. 



Head with dense, irregular punctures; bisinuate in front 

 for base of antennae. Eyes pointed. Antennae not very 

 long, first joint stout and curved, second short, its base 

 curved under apex of first, all the rest closely applied 

 together and strongly inflated, third to seventh each more 

 than twice as wide as long, and with the middle portion 

 more convex than the sides, eighth with its inner side about 

 as long as that of the seventh, but the outer side almost twice 

 as long, ninth about as long as seventh but somewhat 

 narrower, its sides rounded and tip truncated. Prothorax 

 slightly longer than wide, base and apex subequal ; front 

 portion of disc with dense punctures and fine striae, the 

 striae becoming coarser on each side and converging to a 

 sub-basal fovea (but lateral striae and foveae concealed from 

 above), near base with a strong transverse impression 

 traversed by numerous striae. Elytra subelliptic-ovate, 

 greatest width scarcely one-fourth more than that of pro- 

 thorax; base truncate, narrowly raised, and with a row of 

 larger punctures than elsewhere ; with series of not very 

 large but sharply-defined punctures, close together in the rows. 

 Abdomen with numerous (but not crowded) sharply-defined 

 punctures. Legs not very long; femora grooved for reception 

 of tibiae. Length, l^-lf mm. 



Hob. — North-western Australia: Derby, nine specimens 

 from nests of Cremastoqaster, sp. (W. D. Dodd). Type, 

 I. 6714. 



Much smaller than antennaUs, and with the apparent 

 ninth joint of antennae not almost buried in the eighth. 

 There are also many other differences from the description of 

 that species. Some specimens (apparently females) have the 

 abdomen much more convex than others. 



DlPHOBIA MYRMECOPHILA, U. sp. 



Dark castaneous-brown, appendages somewhat paler. 

 Prothorax with a few short, scattered, erect setae, and a
